Jochen Stiepel commented on MNG-4794:
-------------------------------------
I found the cause of this problem!
On the SLES Server there were two JDK's installed. The Sun JDK and an IBM JDK.
JAVA_HOME was pointing to the IBM-JDK and in the PATH the Sun JDK was first:
output of: mvn -version
Apache Maven 3.0-beta-3 (r990787; 2010-08-30 14:44:03+0200)
Java version: 1.6.0
Java home: /usr/lib/jvm/java-1_6_0-ibm-1.6.0/jre
Default locale: de_DE, platform encoding: ISO-8859-1
OS name: "linux" version: "2.6.27.48-0.6-pae" arch: "x86" Family: "unix"
output of (Sun JDK): java -version
java version "1.6.0_21"
Java(TM) SE Runtime Environment (build 1.6.0_21-b06)
Java HotSpot(TM) Client VM (build 17.0-b16, mixed mode, sharing)
output of (IBM-JDK): /usr/lib/jvm/java-1_6_0-ibm-1.6.0/jre/java -version
java version "1.6.0"
Java(TM) SE Runtime Environment (build pxi3260sr8-20100409_01(SR8))
IBM J9 VM (build 2.4, JRE 1.6.0 IBM J9 2.4 Linux x86-32
jvmxi3260sr8-20100401_55940 (JIT enabled, AOT enabled)
J9VM - 20100401_055940
JIT - r9_20100401_15339
GC - 20100308_AA)
JCL - 20100408_01
Then I changed the JAVA_HOME to the Sun-JDK and it works. Afterwards I changed
the JAVA_HOME and the PATH to the IBM-JDK and I'm getting the exception again.
